Application filed .T anuary 15, 1913. Serial-No. 742.299.

To all whom it may concern Be it known that we, WILLIAM R. FUNK andCHARLEY .F. FUNK, citizens of the United States, residing at ArcherCity, in the' county of Archer, State of Texas,'have invented a new anduseful Roller for Railway-Track Jacks, of which the following 1s a`specification.

The present invention relates to railway track jacks, and aims toprovide a roller for the foot of the jack, which shall notencumber thejack, but which shall permit the jack to be readily moved on the railsof thetrack from one place to another.

The jacks which are at present employed in railroad work, such as forraising the rails, and the like, are quite heavy and cumbersome tohandle, and in conveying such jacks from one place or locality toanother, it has been the custom to slide one edge of the foot on thetread of the rails. This method, which is prevalent, is objectionablefor several reasons, among them being the fact that this operation isboth tedious and laborious, and causes considerable wearto the foot ofthe jack, as well as wearing the rail tread.

In many cases, it has been necessary for two or more men to carry ormove a jack from one locality 'to another, and although there aredevices on the market, for moving jacks fromoneplace to another alongthe track, no simple and practical means has been provided, which hascome into any appreciable or extensive use.

It has therefore been the object of the present invention to so journala roller to the foot of the jack, that the foot of the jack will not beencumbered, and to permit the roller to engage the rails, so that thejack may be readily rolled along the rails from one place to anotherwith ease and despatch. This roller has not only been provided so as toeliminate the tedious and laborious operation of sliding the foot of thejack along the rails, but has also been provided to eliminate wear.

With the foregoing general objects out-- lined, and other objects inview which will appear as the description proceeds, the inventionresides in the combination and arrangement of parts and in the detailsof construction hereinafter described and '.claimed. it being understoodthat changes in the precise embodiment of invention herein disclosed canbe made Within the scope of what is claimed without departing from thespirit of the invention.

The invention has been illustrated in its preferred embodiment inthe-accompanying drawing, wherein Figure l is a fragmental perspectiveof an ordinary railway jack, the upper portion thereof being brokenaway. Fig. QA is a fragmental plan view of the foot or base of the jack,parts being shown in section. Figs. 3 and 4 are sectional views on thelines 3-3 and 4-4 of Fig. 2. Fig. 5 is a fragmental view of the roller.

Referring specifically to the drawing, the numeral 6 designates anordinary or prevailing type of jack employe'dfor use in lifting railsand the like, and which is provided with the foot or base 7. Ordinarily,in conveying the jack from one locality to 'the other, the jack issupported in a diagonal or inclined position with one edge of the foot 7contact-ing with the rail, and the jack is moved along the rails, theedge of the foot sliding over the rail treads, which operation is bothtedious and laborious, and causes considerable wear, not only to thefoot, but also to the rails.

In carrying out the present invention the roller 8 has been journaledterminally to one edge of the foot, or to the edge which is usually slidon the rail, this being effected by cutting aportion of the said edgeaway, as indicated by the numeral 9. The roller 8 fits within the cutaway portion 9 wit-h its ends abutting against the ends or shoulders 10of the cut away portion, the outer sido of the roller being preferablyflush with the edge of the foot. At each end, the cut away portion 9 isprovided with a step or bearing 11 with which the corresponding end ofthe roller 8 contacts, the faces 12 of the steps 11 being concaved toreceive the ends of the roller. Thus, the intermediate or main portionof the roller is free or out of contact with the foot, the ends onlybeing journaled.

In order to effectively retain the roller in position, a pair ofU-shaped clips 13 straddle the edge of the foot 7 and have their ends orarms secured to the foot by means of i the bolts, or other securingmembers 14, the

intermediate portions or bends of the clips embracing' the ends of therollers, and slightly overlapping the edge of the foot beyond the endsof the roller. The uppermost arms of the clips are relatively short,whereas the lower arms extend from edge to edge,

the bolts 14 passing throu h the lower arms adjacent the edges 'of theoot, and one pair of bolts passing through the u per arms of the clips.These bolts permit tiie cli s to be removed, so that a jack may be empoyed in the usual manner. These clips 13 effectively retain the rollersin position, and assist in journaling the. ends of the rollers to thefoot, but they do not encumber the foot, so as to preclude the ordinaryor general use of the jack. On the other hand, the attachment isextremely simple, compact, substantial and inexpensive in constructionand may be readily applied to jacks now in use with but little troubleand expense, and renders the jack readily transportable from onelocality to another along t e roadway or track.

From .the foregoing, it will be evident that when the jack is to betransported from one place to another the foot may be readily thrown orlifted onto the rail, with the roller 8 engaging the tread, and bypushing or pulling the jack in the proper direction, the same may bereadily moved along the rail as above intimated, the roller permits thejack to be readily, quickly and conveniently transported and eliminateswear which is incident to sliding the foot of the jack along the rail,as usual.

1. 'A jack having a foot, a portion of one edge of the foot being cutaway, a roller fitting in the cut away portion, and U-shaped clipsembracing the ends of the roller and having their ends secured to theupper and lower faces of the foot. 4

2. A jack having a foot, a portion of one edge of the foot being cutaway and the cut away portion having a step at each end, a rollerfitting in the cut away portion and having its ends bearin agalnst theste s, and U-shaped clips stra dling the said edige of the said foot,and having their arms secured to the upper and lower faces of the foot,the bends of the clips embracing the ends of the roller and overlappingthe said edge of the foot beyond the ends ofthe roller.

3. A jack having a foot, a portion of one edge of the foot being cutaway a roller fitting in the cut away portion, thecut away portionhaving a bearing at each end for the respective end of the roller, andclips secured to the foot and embracing the ends of the roller.

In testimony that we claim the foregoing as our own, we have heretoaiiiXed our signatures in the presence of two witnesses.
